Hi there,
No worries, your English is just fine, a lot of us aren't native speakers. 😉
I've checked the project pages and we've already gave someone permission to translate to French for Masca and the sequel: http://www.evilflowers.com/index.php?/articles.html/completed-projects/masca-r34/
Maybe you could get in touch with them and ask if you can support them?

Sorry for taking so long to reply.
We're aware that it's not completed yet and I'm working slowly on the typesetting. The last chapter is about 70 pages long and I want to release that in one go because it would be awful to split it midway. I'm close to the half of it currently. Whenever I can, I work on it while trying to keep the other projects going as well.
